TOOL FOR PUTTING ON AND REMOVING PNEUMATIC TIRES.

Specification of Letters Patent.

Application fi d March 19, 1909. Serial No. 484,480.

To all whom it may concern:

Be it known that l, LOUIS FELIX Calms, a citizen of the Republic ofFrance, residing in Courbeovic, Seine, France, have invented a new anduseful Improvement in Tools for Putting On and Removing Tires, of whichthe following is a specification.

The present invention has for its subject a tool for facilitating theattachment and detachment of pneumatic tires. The said tool alsoallows.of preventing damage to the cover or jamming of the air tubebetween the rim and the eover, an accident which frequently occurs withthe tools usually employed and causes bursting of'the air tube.

The following description with reference to the accompanying drawingwill enable. the construction and operation of the device to be wellunderstood.

Figures 1 and 2 show the tool in side view and front view respectively;Fig. 3 is a perspective view of a modification; Figs. 4 and 5 are viewson a smaller scale illustrating the use of the tool in putting on anddetaching a pneumatic tire; Fig. P is a transverse section of the outerend of the tool of Figs. 4- and 5. Fig. 6 is a. plan view of anotherform of the apparatus; Figs. 7 and 8 are perspective views of hookswhich may be employed to facilitate the use of the tool.

The apparatus consists of a tube (L having a handle Z) at the end and inwhich slides a rod 0 formed orcprovided with a ring (Z which may itselfbe provided if required with a handle 0. As will be understood, thesliding rod 0 serves to vary the length of the apparatus to adapt it towheels of diller- 'ent diameters.

On the tube a is fixed, by means of a pin 1 for example, a cross piece.j bent up at right angles at the end It to form a hook. At the same sidethe cross piece is made with a shoulder h below, designed to bearagainst the outer flange or face of the rim during dismounting of thetire, as hereinafter described. On the other sidethe cross piece isextended to provide a bearing member in the form of an inclined plane 2and having a shoulder i beneath adapted to bear against the interioredge or face of the rim in putting on the tire. I

The operation of this apparatus is as follows :To remove a pneumatictire the bead of the cover is first as shown in Fig. 5 pushed out of therim by a suitable tool g, which hooks on one of the spokes and keeps thebead of'the cover lifted out of the rim. The hook it is inserted underthe bead, care being taken' that the shoulder h bears against the rim.The ring d is then passed on to the hub of the wheel and the apparatusis turned in the direction shown by the arrow, assuming the wheel toremain fixed, or the wheel is turned in the opposite direction assumingthe apparatus to remain stationary. The head of the cover is thusremoved from the rim all around the wheel. On the other hand, to replacethe tire, after having inserted the head of the cover in the rim bymeans of a suitably shaped tool 8 having its lower part 8 spoon-shapedso as to bear without slipping on one of the spokes, the inclined arm 2'of the cross piece f is inserted so that the shoulder 21 bears againstthe interior edge of the rim; the tool is then turned in the directionof the arrow, Fig. 4, whereby the bead of the cover is pushed back bythe inclined plane 2' and engages progressively in the rim all aroundthe same.

In order to reduce friction at the shoulder la. and the bearing face 2',the part 7' may be constructed as shown in Fig. 3. For the said purposea roller m is fitted in the position of the shouder h and the tirereplacing bearing face is formed by a roller n disposed above the hookedpart 2'. Further the'cross piece carries at right angles to its axis anarm, or two synnnetrical arms, it, set slightly back relatively to theaxis of the tube a, said arms being titted at the end with conicalrollers 7). A roller 0 fitted under the hooked part i serves to reducefriction against the inner side of the rim. In this modification-moreover the ring (Z is replaced by a leather strap which can bebuckled and adapted to the hub of each wheel.

The removal of the tire is effected as before described With thedifference that, as seen in Fig. 8, the cross piece f now bears againstthe outer edge or face of the rim through the medium of the roller m,which greatly eases and facilitates the operation and has the advantageof not damaging the rim. On the other hand, for replacing the cover, thetube a is, as shown in Figs. 3 and 4, turned so that the arm carryingthe roller 72 first lifts the'bead of the cover (see Fig. 4') and at thesame time diverts it to- W'ard the roller 91 which in its turn pushesitback into the rim as seen in Fig. 3, while the curved end of the part ipushes back the air Patented July 19, 1910.

v to the tube a as shown in Fig. 4:.

' around 180 on its axis the piece f may have arms with rollers 72 atboth sides. Instead of bending the tube a into a handle, the latter maybe formed by fitting a T-tube t f may likewise be made adjustable alongthe tube a by forming the latter with holes to receive the fixing pin 9.

What I claim and desire to secure by Letters Patent i: i

1. An apparatus for mounting and ren'ioving pneumatic tires com n'isingan inner member adapted to rotatirely engage the hub of the wheel, anouter member slidingly engaging the inner member, and a cross piece onthe outer member comprising at one side an outward hook /1 adapted. forcngagement with the inner face of the head of the tire and a shoulderfor hearing against the outer face of the rim to cause the removal ofsaid head from within the rim and at the other side an inward hook 6adapted for engagement with the inner face of the edge of the rim andhaving a face i inclined inwardly for guiding the edge of the tireinward.

2. An apparatus for mounting and removing pneumatic tires comprising aninner member adapted to rotatively engage the.

hub of the wheel, an outer member slidingly engaging the inner member,and a cross piece on the outer member comprising at one side an outwardhook 7: adapted for engagement with the inner face of the bead of thetire and a shoulder for bearing against the outer face of the rim tocause the removal of said bead from Within the The part edge of the tireinward and a roller 11 disposed to engage the outer face of the bead ofthe tire at a pointradially outward from said face i to push the tireinto the rim.

3. An apparatus for mounting and removing pneumatic tires comprising aninner member adapted to rotatively engage the hub of the wheel, an outermem ber slidingly engaging the inner member, and a cross piece on theouter member comprising at one side an outward hook it adapted forengagement with the inner face of the head of the tire and a shoulderfor hearing against the outer face of the rim to cause the removal ofsaid head from within the rim, said shoulder carrying an anti-frictionwheel and at the other side an inward hook '2 adapted for engagementwith the inner face of'the edge of the rim and having a face i inclinedinwardly for guiding the edge of the tire inward and a roller n disposedto engage the outer face of the bead of the tire at a point radiallyoutward from said face i to push the tire into the rim, and a roller qin position to support the edge of the tire outside of the rim at apoint in advance of the pushing roller 01.

In witness whereof, I have hereunto si 'ned my name in the presence oftwo subscri Jing witnesses.
